The top of a ladder of inertia m rests against a smooth wall, and the foot rests on the ground. the coefficient of static friction between ground and ladder is μs. what is the smallest angle between the ground and the ladder such that the ladder does not slip? express your answer in terms of some or all of the variables m and μs.

The earth exerts a gravitational force of 500 n on amy. what is amy’s mass in kg?

What is the gravitational attraction between a dating couple whose centers of mass are 0.630 m apart if the boy weighs 715 n and the girl weighs 465 n?

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
